摘要
空气动力学系统的设计与分析是方程式赛车中及其重要的一部分,文章的设计与分析是以北京理工大学珠海学院方程式车队设计的一辆方程式赛车的空气动力学套件为研究对象。首先通过三维建模软件CATIA建立完整的赛车模型,然后将模型导入CFD软件进行数值模拟,最后通过CFD软件分析得出加装空气动力学系统的赛车在风速20 m/s的工况下的负升力从-34 N提高到411 N,加装前翼后前轮受到的阻力减少了约33%。
Aerodynamics system design and analysis is an important part of formula racing. The design and analysis of this paper is based on the aerodynamics package of the formula car designed by the formula team of Beijing Institute of Technology Zhuhai Campus. Firstly, a complete racing model is established by 3D modeling software CATIA, and then the model is imported into CFD software for numerical simulation. Finally, through CFD software analysis, it is concluded that the negative lift of the racing car equipped with aerodynamic system increased from-34 N to 411 N in the wind speed of 20m/s, and the resistance of the front wheel after installing the front wing is reduced by about 33%.
